Since the Content-Disposition header is not always available, you could use a solution that not only looks for that specific header, but also looks at the individual file types within the Content-Type header.

Here is a list of Content-Types. The code below checks the headers for Content-Disposition , but it also checks the headers for some of the Content-Type that are commonly downloadable. I also added a check for the Content-Length, because it could be useful in chunking the file being downloaded.

Content-Disposition provides filename information if it is not given in the url. But this information is not always present, as is the case with your url.

A solution is to filter by content type, see the example below. I think your former code works but with a slight modification. It's trying to download the complete file due to which it's getting hanged every time you run. This is not explained in user documentation. But by a guess we can say , chunked transfer encoding is being done, the data stream is divided into a series of non-overlapping "chunks". The chunks are sent out independently of one another by the server.

You could check the content-type response header. This header defines the media type of the requested resource. The most common types are shown here. The parameter value is not mandatory but type and subtype are. There are currently 7 types as defined by RFC :. The header you are looking for varies with the resource you are expecting, but some examples you may use.

It is worth noting the types are fixed, you cannot define a new subtype but you can define a new subtype. How are we doing? Please help us improve Stack Overflow. Take our short survey.
